| 摘 要： | 祁连山西段诸盆地地下水的形成与分布不仅取决于第四系厚度、孔隙、冻土等条件，更重要的还取决于山前平原与基岩的接触关系及其地质结构。盆地内地表水与地下水的相互转化，不仅使地下水的水质、水量具明显的水平分带性，而且也影响着主干河流流量的大小。在海拔３８００ｍ以上多年冻土区，地下水以冻结层上水和冻结层下水形式存在；在海拔３８００ｍ以下非多年冻土区，地下水主要以潜水形式存在，富水性中等或强。诸盆地地下水主要以ＨＣＯ３－Ｃａ－Ｍｇ型水为主，水质优良

| Abstract: | The form and disturbution of the basins on the west section of Qilianshan were decided by the Quaterary depth,pore and frozen ground et al.conditions.All the more important,by the contact relation beween plains on the front of mountains and basement rocks and the geological structure.Qwing to inversion of surface water and ground water each other in the basins not only the quality and quantity of ground water had the makings of obvious horizontal zones,but also affected the volumes of the master stream.In the frozen ground arear above altitude 3 800m during years the forms of ground water are the water above frozen layer and below frozen layer.In non frozen ground arear below altitude 3 800m during years,the form of ground water is mainly phreatic water.Its productive nature is medium or rich.Ground water of the basins belongs mainly to HCO 3 Ca Mg type,and water quality is fine. |
